FIG. 3 is a functional block diagram illustrating the handheld device 1of the present embodiment. Functional blocks of the handheld device 1are controlled by the control unit 1010.

The control unit 1010 operates on the CPU 101 with which the handhelddevice 1 illustrated in FIG. 2 is equipped, includes a userauthentication unit 1011, a state determination unit 1012, a lockcontrol unit 1013, an application start unit 1014, and the like, andcontrols a memory 1030, a static biometric information acquisition unit1110, a dynamic biometric information acquisition unit 1120, acommunication unit 1310, or the like based on an instruction given froma user interface 1040 such that the static biometric information and thedynamic biometric information are acquired, stored, and compared, thehandheld device 1 is locked or unlocked, or an application starts.

The user interface 1040 is configured with the operation device 104, theaudio input device 141, the audio output device 142, the video inputdevice 151, the display device 152, and the like which are illustratedin FIG. 2, and presents the user with various kinds of information andtransfers the instruction of the user to the control unit 1010.

The static biometric information acquisition unit 1110 is configuredwith the fingerprint sensor 111 and the like which are illustrated inFIG. 2 and detects a fingerprint and the like which are the staticbiometric information of the user who uses the handheld device 1.

The dynamic biometric information acquisition unit 1120 is configuredwith the heart rate sensor 112, the blood pressure sensor 113, thetemperature sensor 114, and the like which are illustrated in FIG. 2,and measures the heart rate, the blood pressure, the body temperature,and the like which are the dynamic biometric information of the user whowears the handheld device 1.

The communication unit 1310 is configured with the mobile communicationdevice 131, the LAN communication device 132, the short-range wirelesscommunication device 133, and the like which are illustrated in FIG. 2and performs acquisition of an application and transmission reception ofvarious kinds of data.

The memory 1030 is configured with the memory 103 and the like which areillustrated in FIG. 2, and stores static biometric information 1031,dynamic biometric information 1032, an application 1033, a permissionlevel table 1034 which is a table of levels at which applications arepermitted to start, and the like, in addition to the program and variouskinds of setting information for controlling the handheld device 1.

The static biometric information 1031 is, for example, a fingerprint ofthe authorized user acquired through the static biometric informationacquisition unit 1110. Before the handheld device 1 is used, the staticbiometric information of the authorized user is registered in advance.

The dynamic biometric information 1032 is, for example, the heart rate,the blood pressure, and the body temperature of the user acquiredthrough the dynamic biometric information acquisition unit 1120. Whenthe handheld device 1 is used, for example, the dynamic biometricinformation of the user in the normal state is measured and registered.

The application 1033 is an application program acquired through thecommunication unit 1310 or an application program which ispre-installed. A plurality of application programs can be registered,and an application permission level can be registered in the permissionlevel table 1034 in association with each application program.

The user authentication unit 1011 determines whether or not the user isan authorized user by comparing the static biometric informationacquired through the static biometric information acquisition unit 1110when the handheld device 1 is used with the static biometric information1031. When the user is authenticated to be the authorized user, the lockcontrol unit 1013 is controlled such that the handheld device 1 isunlocked.

The lock control unit 1013 is controlled by the user authentication unit1011 such that the lock control unit 1013 unlocks the handheld device 1,and, for example, when the user interface 1040 is not operated for acertain period of time, the lock control unit 1013 locks the handhelddevice 1. Further, even when the state determination unit 1012 isdetermined to be in a sleep state, the lock control unit 1013 locks thehandheld device 1.

The state determination unit 1012 determines the state of the user bycomparing the dynamic biometric information acquired through the dynamicbiometric information acquisition unit 1120 when the handheld device 1is used with the dynamic biometric information 1032, and controls thelock control unit 1013 and the application start unit 1014. For example,when the user is determined to be in the sleep state, the lock controlunit 1013 is controlled such that the lock control unit 1013 locks thehandheld device 1. Further, when the user is determined to be in thenormal state, all applications are set to enter a startable state, andwhen the user is determined to be in a stress state, applications thatcan be started are limited. Applications to be limited are registered inthe permission level table 1034. A start permission level of eachapplication may be decided in advance and may be registered by the userthrough the user interface 1040.

An application to be started is not limited to the application 1033stored in the memory 1030, and an application on the network 6 may bestarted through the communication unit 1310.

FIG. 4 is a flowchart illustrating an application permission operationof the handheld device 1 of the present embodiment. This flowchartillustrates a process of performing the user authentication through thehandheld device 1, checking the state of the user, and limiting anapplication to be started according to the state of the user. First, thestatic biometric information is detected, and the user authentication isperformed. The static biometric information acquisition unit 1110acquires the static biometric information, and the user authenticationunit 1011 performs the user authentication as to whether or not theacquired static biometric information is identical to the staticbiometric information 1031 which is registered in advance by comparingthe acquired static biometric information with the static biometricinformation 1031 (S401). For example, the fingerprint serving as thestatic biometric information is detected, the user authentication isperformed, and when the detected fingerprint is determined to beidentical to the registered fingerprint, the lock control unit 1013unlocks the handheld device 1 (S402), and the application start unit1014 permits a start of an application of the permission level 1 (S403).

For example, the application of the permission level 1 is an applicationthat does not relate to information of the user him/herself and has noparticular problem even when it is used by anyone else such as a clockapplication, a web browser, a map application, a camera application, aweather forecast application, a music application, a calculatorapplication, a dictionary application, a game application, and anavigation application. The permission level of each application isregistered in the permission level table 1034.

A display example of a screen of the handheld device 1 at this time isillustrated in FIG. 5A. The clock application, the web browser, the mapapplication, the calculator application, and the dictionary applicationare the applications of the permission level 1 and thus are in thestartable state, and the other applications have a different icon colorwhich indicates that they are in the non-startable state.

The user authentication may be performed through any other biometricauthentication such as a vein authentication, a face authentication, aniris authentication, or a retina authentication, in addition to thefingerprint authentication, and for example, when the handheld device 1is worn on the wrist, the user authentication may be performed throughthe vein authentication for the part on which the handled device 1 isworn, so that a situation in which anyone else wears the handheld device1 and pretends to be the authorized user can be prevented.Alternatively, the unlocking operation may be performed by inputting apasscode, and a pattern lock may be released by the trajectory of thefinger.

Generally, there is no difference between a period of time in which thestatic biometric information for the fingerprint authentication, thevein authentication, the face authentication, the iris authentication,the retina authentication, or the like is acquired and a period of timein which the passcode is input, and a period of time taken until theapplication of the permission level 1 enters the startable state isabout several seconds.

Then, the dynamic biometric information is detected, and the state ofthe user is determined. The state of the user is determined such thatthe dynamic biometric information acquisition unit 1120 acquires thedynamic biometric information, and the state determination unit 1012compares the acquired dynamic biometric information with the dynamicbiometric information 1032 that is registered in advance (S404).

For example, the heart rate, the blood pressure, and the bodytemperature which are the dynamic biometric information are measured inthe normal state and registered in the dynamic biometric information1032, the dynamic biometric information acquisition unit 1120 measuresthe heart rate, the blood pressure, and the body temperature, and whenthe heart rate, the blood pressure, and the body temperature are equalto or less than lower limit values in the normal state, the sleep stateis determined. Further, for example, when the heart rate and the bloodpressure are equal to or larger than upper limit values in the normalstate, the stress state is determined, and a state which corresponds toneither the sleep state nor the stress state is determined to be thenormal state.

Generally, a period of time in which the dynamic biometric informationsuch as the heart rate, the blood pressure, the body temperature, thebrain wave, or the amount of sweating is acquired is longer than aperiod of time in which the static biometric information is acquired,and a period of time taken until applications of permission levels 2 and3 (which will be described later) enter the startable state is aboutseveral tends of seconds. For this reason, acquisition of the dynamicbiometric information may start at the same time as when acquisition ofthe static biometric information starts, or the dynamic biometricinformation may be constantly acquired, and the state determination maybe performed based on the biometric information obtained for previous 30seconds.

First, the process is switched according to whether or not the state ofthe user is the sleep state (S405). When the state of the user isdetermined to be the sleep state, the handheld device 1 is locked(S410), and the process ends (the permission level 0). For example, whenthe user is asleep in a station, a park, or the like, although anotherperson causes the handheld device 1 to touch the finger of the user andperform the fingerprint authentication, if the heart rate, the bloodpressure, and the body temperature are equal to or less than the lowerlimit values in the normal state, the state of the user is determined tobe the sleep state, and thus the handheld device 1 can be locked.

When the state of the user is determined not to be the sleep state, theprocess is switched according to whether or not the state of the user isthe stress state (S406). When the state of the user is determined to bethe stress stat, the applications of the permission levels 1 and 2 arepermitted to be started (S407).

For example, the application of the permission level 2 is an applicationthat relates to the user him/herself and is considered to have a problemwhen it is used by anyone else such as a schedule application, a mailapplication, a photo application, a telephone application, or an addressbook application. The application of the permission level 2 is anapplication which is considered to have no particular problem regardlessof the state of the user when the user is the authorized user. A displayexample of a screen of the handheld device 1 at this time is illustratedin FIG. 5B. In addition to the fact that the applications of thepermission level 1 are in the startable state, the schedule applicationand the mail application are the applications of the permission leveland thus are in the startable state, and the other applications have adifferent icon color which indicates that they are in the non-startablestate.

When the state of the user is determined not to be the stress state(determined to be the normal state), all applications of the permissionlevels 1 to 3 are permitted to be started (S408).

For example, the application of the permission level 3 is an applicationthat relates to information of the user him/herself and is considered tohave a big problem when it is used by anyone else such as an e-moneyapplication or an online banking application. The application of thepermission level 3 is an application which is considered to have aproblem depending on the state of the user even when the user is theauthorized user.

For example, when the user is panicked and unable to make consciousdetermination due to a bank transfer fraud or the like or when the useris coercive to perform an operation by another person, if the heart rateand the blood pressure are equal to or larger than the upper limitvalues in the normal state, the state of the user is determined to bethe stress state, and the e-money application, the online bankingapplication, and the like can be set not to be started.

FIG. 5C illustrates a display example of the screen of the handhelddevice 1 when all applications are permitted to be started. In additionto the fact that the application of the permission level 1 and theapplication of the permission level 2 are in the startable state, thee-money application and the online banking application are theapplications of the permission level 3 and thus are in the startablestate, and it is indicated that all applications are in the startablestate.

Then, the process is switched according to whether or not apredetermined period of time has elapsed while the user does not performan operation (S409). When a predetermined period of time (for example,10 seconds) has elapsed, the handheld device 1 is locked (S410), and theprocess ends.

When a predetermined period of time has not elapsed, the process returnsto step S404, and the process is continued. For example, when the stateof the user is determined to be the stress state, and the application ofthe permission level 3 enters the non-startable state, if the state ofthe user returns to the normal state later, all applications enter thestartable state. Thereafter, when the state of the user is determined tobe the stress state again, the application of the permission level 3enters the non-startable state, and when the state of the user isdetermined to be the sleep state, the handheld device 1 is locked.

The permission level of each application may be decided in advance bythe handheld device 1 or may be set to be changed by the user.

The upper limit values and the lower limit values of the heart rate, thebody temperature, and the blood pressure in the normal state may bedecided in advance by the handheld device 1, but when the heart rate,the body temperature, and the blood pressure of the user are measuredand learned, and the upper limit values and the lower limit values areobtained based on them, more accurate determination can be performed.

Commonly, in the sleep state, the heart rate, the blood pressure, andthe body temperature decrease, and in the stress state, the heart rateand the blood pressure increase, but when the user measures andregisters the heart rate, the body temperature, and the blood pressurein the sleep state and the stress state in advance, more accuratedetermination can be performed. Further, even when anyone else wears thehandheld device 1 and causes the handheld device 1 to touch the fingerof the authorized user and perform the fingerprint authentication, theheart rate, the body temperature, and the blood pressure are detected tobe different from a tendency toward previous measured values of theauthorized user, and in this case, the handheld device 1 may be locked.

The determination of the state of the user may be performed based onother dynamic biometric information such as the brain wave or the amountof sweating in addition to the heart rate, the blood pressure, and thebody temperature.

Further, the terminal device 1 may perform the user authentication basedon the dynamic biometric information obtained from a heart ratewaveform, a brain wave, or the like instead of the static biometricinformation obtained from the fingerprint or the like.

As described above, according to the present embodiment, an applicationsoftware start-up method of an information processing device includesperforming user authentication based on static biometric information,determining a state of a user by comparing dynamic biometric informationacquired from a body of the user with dynamic biometric informationwhich is measured in advance, and limiting application software to bestarted according to the determined state of the user based on apermission level which is set to each application software in advance.Further, the information processing device is forcibly locked accordingto the determined state of the user.

Further, an information processing device includes a static biometricinformation acquisition unit that acquires static biometric information,a user authentication unit that performs user authentication bycomparing the acquired static biometric information with staticbiometric information which is registered in advance, a dynamicbiometric information acquisition unit that acquires dynamic biometricinformation from a body of the user, a state determination unit thatdetermines a state of the user by comparing the acquired dynamicbiometric information which is measured in advance, a lock control unitthat unlocks the information processing device through theauthentication of the user authentication unit, and an application startunit that starts application software which is selected by the useramong a plurality of pieces of application software, wherein theapplication start unit limits application software to be startedaccording to the state of the user determined by the state determinationunit based on a permission level which is set to each applicationsoftware in advance. Further, the lock control unit forcibly locks theinformation processing device according to the state of the userdetermined by the state determination unit.

Accordingly, in the present embodiment, it is determines whether or notthe user is the authorized user based on the static biometricinformation, the state of the user is determined based on the dynamicbiometric authentication, and the start of an application is limitedstepwise according to the state of the user. Thus, when determination ofthe user is suspected, it is possible to limit the start of the specificapplication, for example, when it is against the user's will.

The communication with the handheld device 3 is performed through theshort-range wireless communication device 133.

FIG. 9 is a functional block diagram illustrating the handheld device 3according to the present embodiment. In FIG. 9, the same components asthose in FIG. 3 which is a functional block diagram illustrating thehandheld device 1 according to the first embodiment are denoted by thesame reference numerals. In FIG. 9, the components of the handhelddevice 3 include the dynamic biometric information acquisition unit1120, the dynamic biometric information memory 1032, and the statedetermination unit 1012 among the components of FIG. 3, and thus adetailed description thereof is omitted.

The functional blocks of the handheld device 3 are controlled by thecontrol unit 3010. The control unit 3010 operates on the CPU 101 withwhich the handheld device 3 illustrated in FIG. 7 is equipped, includesthe state determination unit 1012 and the like, and controls the dynamicbiometric information acquisition unit 1120, a memory 3030, acommunication unit 3310, and the like based on an instruction given froma user interface 3040 such that the dynamic biometric information isacquired, stored, transmitted, and displayed.

The user interface 3040 is configured with the operation device 104, theaudio output device 142, the display device 152, and the like which areillustrated in FIG. 7, and presents the user with various kinds ofinformation and transfers the instruction of the user to the controlunit 3010.

The memory 3030 is configured with the memory 103 and the like which areillustrated in FIG. 7, and stores a program and various kinds of settinginformation for controlling the handheld device 3.

The state determination unit 1012 determines the state of the user bycomparing the dynamic biometric information acquired through the dynamicbiometric information acquisition unit 1120 when the handheld device 3is used with the dynamic biometric information 1032, and transmits thestate of the user to the handheld device 2 through the communicationunit 3310.

For example, when the user is determined to be in the sleep state, thesleep state is transmitted to the handheld device 2 through thecommunication unit 3310, so that the handheld device 2 is locked.Further, an application to be started in the handheld device 2 islimited according to the state of the user. Further, when the user isdetermined to be in the normal state, all applications are set to enterthe startable state, and when the user is determined to be in the stressstate, applications that can be started are limited.

FIG. 10 is a flowchart illustrating an application permission operationof the handheld devices 2 and 3 of the present embodiment. Thisflowchart illustrates a process of performing the user authenticationthrough the handheld device 2, checking the state of the user throughthe handheld device 3, and limiting an application to be startedaccording to the state of the user.

First, the handheld device 2 detects the static biometric information,and performs the user authentication (S1001). For example, it isdetermined whether or not the user is the authorized user through thefingerprint authentication. In other words, a fingerprint patterndetected when the user touches the fingerprint sensor 211 with thefinger is compared with the fingerprint pattern of the user registeredin the memory 203, and it is determined whether or not the twofingerprints are identical to each other. When the two fingerprints aredetermined to be identical to each other, the handheld device 2 isunlocked (S1002), and the application of the permission level 1 ispermitted to be started (S1003).

A display example of a screen of the handheld device 2 at this time isillustrated in FIG. 11A. The clock application, the web browser, the mapapplication, the camera application, the weather forecast application,the music application, the calculator application, and the dictionaryapplication are the applications of the permission level 1 and thus arein the startable state, and the other applications have a different iconcolor which indicates that they are in the non-startable state.

The user authentication may be performed through any other biometricauthentication such as the vein authentication, the face authentication,the iris authentication, or the retina authentication, the unlockingoperation may be performed by inputting a passcode, and a pattern lockmay be released by the trajectory of the finger.

The handheld device 3 measures the heart rate through the heart ratesensor 312, measures the blood pressure through the blood pressuresensor 313, and measures the body temperature through the temperaturesensor 314 (S1011).

The handheld device 2 requests the handheld device 3 to confirm thestate of the user through a short-range wireless communication device233 (S1012).

The handheld device 3 detects the dynamic biometric information, anddetermines the state of the user (S1013). For example, the state of theuser is determined based on a result of measuring the heart rate, theblood pressure, and the body temperature. In other words, for example,when the heart rate, the blood pressure, and the body temperaturemeasured through the heart rate sensor 312, the blood pressure sensor313, the temperature sensor 114 of the handheld device 3 are equal to orless than the lower limit values in the normal state, the state of theuser is determined to be the sleep state. Further, for example, when theheart rate and the blood pressure are equal to or larger than the upperlimit values in the normal state, the state of the user is determined tobe the stress state, and the state which corresponds to neither thesleep state nor the stress state is determined to be the normal state.

The handheld device 3 constantly acquires the dynamic biometricinformation, and performs, for example, the state determination based onthe biometric information obtained for previous 30 seconds.

Then, the handheld device 3 transmits the state of the user to thehandheld device 2 through the short-range wireless communication device333 as a response (S1014).

The handheld device 2 switches the process according to whether or notthe state of the user received through the short-range wirelesscommunication device 233 is the sleep state (S1005). When the state ofthe user is determined to be the sleep state, the handheld device 2 islocked (S1010), and the process ends.

Further, even when the user does not wear the handheld device 3 or evenwhen the terminal device 3 does not transmit the state of the user tothe handheld device 2 as a response, the handheld device 2 is locked,and the process ends.

Steps S1006 to 1009 which are processes performed when the state of theuser is determined not to be the sleep state are similar to steps S406to 409 of FIG. 4 in the first embodiment, and thus a detaileddescription thereof is omitted.

A display example of the screen of the handheld device 2 when theapplications of the permission levels 1 and 2 are permitted to bestarted in S1007 is illustrated in FIG. 11B. In addition to the factthat the applications of the permission level 1 are in the startablestate, the schedule application, the mail application, the photoapplication, the telephone application, and the address book applicationare the applications of the permission level 2 and thus are in thestartable state, and the other applications have a different icon colorwhich indicates that they are in the non-startable state.

A display example of the screen of the handheld device 2 when all theapplications of the permission levels 1 to 3 are permitted to be startedin S1008 is illustrated in FIG. 11C. In addition to the fact that theapplications of the permission levels 1 and 2 are in the startablestate, the e-money application and the online banking application arethe applications of the permission level 3 and thus are in the startablestate, and it is indicated that all applications are in the startablestate.

In the present embodiment, the handheld device 3 determines the state ofthe user, but the handheld device 3 may not determine the state of theuser but transmit the measured values of the heart rate, the bloodpressure, and the body temperature to the handheld device 2, and thehandheld device 2 may determine the state of the user.

Further, the terminal device 2 may not perform the user authenticationfor the user, and the terminal device 3 may control whether or not theterminal device 2 is locked by performing the user authenticationthrough the fingerprint authentication or the like and transmitting anauthentication result to the terminal device 2. At this time, theterminal device 3 may perform the user authentication based on thedynamic biometric information obtained from the heart rate waveform, thebrain wave, or the like rather than the static biometric informationobtained from the fingerprint or the like.

In the present embodiment, the example in which the number of handhelddevices is 2 has been described, but the number of handheld devices maybe three or more, and the authentication function and the statedetermination function may be separated. In other words, the systemincluding a plurality of handheld devices according to the presentembodiment can be understood to be an application software start-upsystem including a plurality of information processing devices.

As described above, according to the present embodiment, an applicationsoftware start-up method of an information processing device including aplurality of information processing devices includes performing, by atleast one of the information processing devices, user authenticationbased on static biometric information of a body of a user, determining,by another information processing device, a state of a user by comparingdynamic biometric information acquired from the body of the user withdynamic biometric information which is measured in advance, and limitingapplication software to be started according to the determined state ofthe user based on a permission level which is set to each applicationsoftware in advance.

Further, An application software start-up system includes first andsecond first information processing devices, the first informationprocessing device includes a static biometric information acquisitionunit that acquires static biometric information of a body, a userauthentication unit that performs user authentication by comparing theacquired static biometric information with static biometric informationwhich is registered in advance, a lock control unit that unlocks ahandheld device through the authentication of the user authenticationunit, an application start unit that starts application software whichis selected by a user among a plurality of pieces of applicationsoftware, and a first communication unit that receives a state of theuser from the second information processing device, and the secondinformation processing device includes a dynamic biometric informationacquisition unit that acquires dynamic biometric information from thebody of the user, a state determination unit that determines a state ofthe user by comparing the acquired dynamic biometric information whichis measured in advance, and a second communication unit that transmitsthe determined state of the user to the first information processingdevice, wherein the application start unit limits application softwareto be started according to the state of the user received from the firstcommunication unit based on a permission level which is set to eachapplication software in advance.

Accordingly, in the present embodiment, the same effects as in the firstembodiment are obtained, and when a plurality of handheld devices areregistered in advance, and the user authentication function and thestate determination function are distributed, each handheld device canbe worn on a part of the body suitable for acquisition of each biometricinformation, and thus the handheld devices can be implemented in a formoptimal for the respective functions.

Third Embodiment

FIG. 12 is a flowchart illustrating an application permission operationof the handheld device 1 of the present embodiment. In FIG. 12, stepsS1201 to S1204 are similar to steps S401 to S404 of FIG. 4 in the firstembodiment, and thus a description thereof is omitted.

In step S1205, the process is switched according to whether or not thestate of the user is the sleep state. When the state of the user isdetermined to be the sleep state, the handheld device 1 is locked(S1210), and the process ends. When the state of the user is determinednot to be the sleep state in step S1205, all the applications of thepermission levels 1 to 3 are permitted to be started (S1208).

Here, the process is switched according to whether or not the state ofthe user is the stress state (S1206). When the state of the user isdetermined to be the stress stat, if the user selects the application ofthe permission level 3, a caution screen is displayed (S1221), and it isstarted only when the user confirms it. When the state of the user isdetermined not to be the stress state (determined to be the normalstate), the caution screen is not displayed.

For example, when the application of the permission level such as thee-money application or the online banking application is requested to bestarted, an application software start confirmation screen illustratedin FIG. 13 is displayed on the display device 152.

Steps S1209 to S1210 are similar to steps S409 to S410 of FIG. 4, andthus a description thereof is omitted.

The determination of the state of the user may be performed based onother dynamic biometric information such as the brain wave or the amountof sweating in addition to the heart rate, the blood pressure, and thebody temperature.

In the present embodiment, the example in which the number of handhelddevices is 1 has been described, but the number of handheld devices maybe two or more, and the authentication function and the statedetermination function may be separated.

Through the above configuration, in the present embodiment, the sameeffects as in the first embodiment can be obtained, and since it ischecked when a specific application is started according to the state ofthe user, for example, when determination of the user is suspected, itis possible to encourage reconsideration of the start of the specificapplication.

Fourth Embodiment

FIG. 14 is a flowchart illustrating an application permission operationof the handheld device 1 of the present embodiment. In FIG. 14, stepsS1401 to S1403 are similar to steps S401 to S403 of FIG. 4, and thus aprocess of inputting a passcode (S1431 to S1433) is added.

First, the static biometric information is detected, and the userauthentication is performed. The static biometric informationacquisition unit 1110 acquires the static biometric information, and theuser authentication unit 1011 performs the user authentication as towhether or not the acquired static biometric information is identical tothe static biometric information 1031 which is registered in advance bycomparing the acquired static biometric information with the staticbiometric information 1031 (S1401). For example, the fingerprint servingas the static biometric information is detected, the user authenticationis performed, and when the detected fingerprint is determined to beidentical to the registered fingerprint, the process proceeds to stepS1431. The user authentication may be performed through any otherbiometric authentication such as the vein authentication, the faceauthentication, the iris authentication, or the retina authentication,in addition to the fingerprint authentication.

Then, the process is switched according to whether or not a sleep statedetection log (which will be described later) in the memory 103 (S1431).When there is no sleep state detection log, the process proceeds to stepS1402, and the lock control unit 1013 unlocks the handheld device 1, andthe application start unit 1014 permits the start of the application ofthe permission level 1 (S1403).

When there is a sleep state detection log, the process proceeds to stepS1432, a passcode input request screen illustrated in FIG. 15 isdisplayed, and the process proceeds to step S1402 when a passcode whichis information other than the biometric information input from the userinterface 1040 such as the operation device 104 or the audio inputdevice 141 is identical to a passcode which is set in advance in stepS1433. A pattern lock may be released by the trajectory of the fingerinstead of the passcode.

Steps S1404 to S1410 are similar to step S404 to S410 of FIG. 4, but aprocess of recording the sleep state detection log (S1434) is added.

When the state of the user is determined to be in the sleep state instep S1405, since it is suspected that anyone else causes the handhelddevice 1 to touch the finger of the user and perform the userauthentication, in step S1434, position information which is a place inwhich the user authentication is performed is specified through the GPSreceiver 121 and recorded as a log together with time information, thehandheld device 1 is locked (S1410), and the process ends. The log isrecorded in the memory 103.

Further, in step S1434, a warning may be displayed on the display device152, a vibrator for an incoming call may be operated, a photograph or avideo may be captured through the video input device 151, attached to ane-mail together with the log, and transmitted to an address which isdesignated in advance.

In the present embodiment, the example in which the number of handhelddevices is 1 has been described, but the number of handheld devices maybe two or more, and the authentication function and the statedetermination function may be separated.

Through the above configuration, in the present embodiment, the sameeffects as in the first embodiment can be obtained, and when thehandheld device is likely to be operated by anyone else, a warning isdisplayed, a photograph is captured, and a log is recorded, and thus itcan be expected that a family member or anyone else is prevented fromfurtively looking at an e-mail. Further, when the log is recorded, it isnecessary to input the passcode in order to lock the handheld device,and thus it is possible to prevent anyone else from performing theunlocking operation.

Fifth Embodiment

FIG. 16 is a flowchart illustrating an application permission operationof the handheld device 1 of the present embodiment. In FIG. 16, stepsS1601 to S1603 are similar to steps S401 to S403 of FIG. 4 in the firstembodiment, and thus a process of inputting a passcode (S1631 to S1633)is added.

First, the static biometric information is detected, and the userauthentication is performed. The static biometric informationacquisition unit 1110 acquires the static biometric information, and theuser authentication unit 1011 performs the user authentication as towhether or not the acquired static biometric information is identical tothe static biometric information 1031 which is registered in advance bycomparing the acquired static biometric information with the staticbiometric information 1031 (S1601). For example, the fingerprint servingas the static biometric information is detected, the user authenticationis performed, and when the detected fingerprint is determined to beidentical to the registered fingerprint, the process proceeds to stepS1631. The user authentication may be performed through any otherbiometric authentication such as the vein authentication, the faceauthentication, the iris authentication, or the retina authentication,in addition to the fingerprint authentication.

Then, the process is switched according to whether or not there is aperiod of time in which it is unable to measure the dynamic biometricinformation after the handheld device 1 is previously unlocked (S1631).When there is not period of time in which it is unable to measure thedynamic biometric information, the process proceeds to step S1602, thelock control unit 1013 unlocks the handheld device 1, and theapplication start unit 1014 permits the start of the application of thepermission level 1 (S1603).

When there is a period of time in which it is unable to measure thedynamic biometric information, since anyone else is likely to wear thehandheld device 1, cause the handheld device 1 to touch the finger ofthe user, and perform the user authentication, the passcode inputrequest screen illustrated in FIG. 15 is displayed on the handhelddevice 1, and when the input passcode is identical to the passcode whichis set in advance in step S1633, the process proceeds to step S1602. Apattern lock may be released by the trajectory of the finger instead ofthe passcode.

Steps S1604 to S1610 are similar to step S404 to S410 of FIG. 4, andthus a description thereof is omitted.

In the present embodiment, the example in which the number of handhelddevices is 1 has been described, but the number of handheld devices maybe two or more, and the authentication function and the statedetermination function may be separated.

Through the above configuration, in the present embodiment, the sameeffects as in the first embodiment can be obtained, and when thehandheld device is removed, it is necessary to input the passcode inorder to unlock the handheld device next time, and thus it is possibleto prevent anyone else from performing the unlocking operation.

FIG. 17 is a flowchart illustrating an application permission operationof the handheld device 1 of the present embodiment. In FIG. 17, stepsS1701 to S1710 are similar to steps S401 to S410 of FIG. 4 in the firstembodiment, and thus a process of switching an application according toa current position (S1741) is added.

In step S1706, the process is switched according to whether or not thestate of the user is the stress state. When the state of the user isdetermined to be the stress state, the applications of the permissionlevels 1 and 2 are permitted to be started (S1707). When the state ofthe user is determined not to be the stress state (determined to be thenormal state), the process is switched according to the current positionof the handheld device 1 (S1741). The current position is specifiedthrough the GPS receiver 121, and when the current position is apredetermined position which is set in advance, all the applications ofthe permission levels 1 to are permitted to be started (S1708). Thepredetermined position is, for example, the user's home or company orthe like. When the current position is not a predetermined positionwhich is set in advance, the applications of the permission levels 1 and2 are permitted to be started (S1707).

Alternatively, all the applications of the permission levels 1 to 3 maybe permitted to be started at a predetermined timing which is set inadvance.

Alternatively, a face photograph of the user may be registered, and allthe applications of the permission levels 1 to 3 may be permitted to bestarted when a face is captured through the video input device 151, andthe user is recognized. Alternatively, all the applications of thepermission levels 1 to 3 may be permitted to be started when the user isrecognized, but anyone else around the user except the user is notrecognized.

The determination of the state of the user may be performed based onother dynamic biometric information such as the brain wave or the amountof sweating in addition to the heart rate, the blood pressure, and thebody temperature.

In the present embodiment, the example in which the number of handhelddevices is 1 has been described, but the number of handheld devices maybe two or more, and the authentication function and the statedetermination function may be separated.

Through the above configuration, in the present embodiment, the sameeffects as in the first embodiment can be obtained, and a specificapplication is permitted to be started when the user is at a safeposition which is set in advance, and thus it is possible to limit thestart of the application at a place which is not assumed by the user.
